An electromagnetic pulse generator (EMP) is an anti-electronics weapon that mimics the intense EM radiation created by a nuclear explosion in an atmosphere. The resulting EM field couples with nearby electronics systems, inducing massive, damaging electrical currents.

An electromagnetic pulse ('''EMP''') generator is an anti-electronics weapon that mimics the intense EM radiation created by a nuclear explosion in an atmosphere. The resulting EM field couples with nearby electronics systems, inducing electrical currents and voltages, thus damaging sensitive electronic equipment.
Just before the [[Cylon attack]], "electric pulse generators" were being transported to [[The Twelve Colonies (RDM)#Caprica|Caprica]] from Battlestar ''[[Galactica]]'' on ''[[Colonial Heavy 798]]'' (later ''[[Colonial One]]''), presumably to place in a planet side museum or school as a historical artifact, or for re-use on another ship ([[Miniseries]]).
Pulse generators are able to act independently, at some level, without needing to be connected to a ship's power grid. They may be an offshoot of, or connected to, [[FTL]] technology due to its employment of hyperspace principles {{TRS|Miniseries, Night 2}}.
As the destruction of the ship by a [[Cylons (RDM)|Cylon]] raid was imminent from nuclear missiles, [[Lee Adama]] activated the devices, giving the appearance that ''Colonial One'' had been destroyed by a nuclear blast. This attempt was successful, as the Cylons cut off the assault, the missiles were disabled, and ''Galactica's'' [[Dradis]] confirmed the ship as destroyed. ''Colonial One's'' electronic systems seemed to be fully functional after the attack.
== Practical Use ==
Just before the [[Fall of the Twelve Colonies|Cylon attack]], electric pulse generators are being transported to [[The Twelve Colonies of Kobol#Caprica|Caprica]] from the decommissioned [[Galactica type battlestar|battlestar]] ''{{RDM|Galactica}}'' on ''[[Colonial Heavy 798]]'' for a purpose unknown to {{callsign|Apollo}} {{TRS|Miniseries, Night 1}}.
It is probable that these devices are standard equipment aboard ships such as battlestars, given Lee Adama's knowledge about the electric pulse generators. It is also probable that such devices were part of a battlestar's fighting tactics against Cylon attacks, since (at least in the first [[Cylon War]], although [[Cylon agent|not in the second]]), Cylons were purely mechanical and thus vulnerable to EMP attacks unless shielded from the effect. Given that a non-military craft such as ''Colonial One'' recovered very shortly after the pulse, even Colonial civilian vessels seem to be equipped with EMP-shielded electronics.
As the destruction of the ship by [[Cylons (RDM)|Cylon]] nuclear missiles is imminent, Lee Adama activates the devices, giving the appearance that ''Colonial One'' had been destroyed by a nuclear blast. This ruse is successful, as the Cylons do not immediately return. The missiles were disabled by the EMP with an energy pulse so strong that ''Galactica''{{'|s}} [[DRADIS]] picks up the pulse, which leaves [[William Adama]] grieving for the apparent loss of his last son {{TRS|Miniseries, Night 2}}.

However, this is scientifically incorrect, because although the human nervous system works with electrical currents, there is no metal to act as antenna for the magnetic field and induce a damaging current.

==Notes==
Although being called an EMP by [[Helena Cain|Admiral Cain]], this effect is not an electromagnetic pulse in the strictest sense, since an EM field is only created when a nuclear detonation's gamma-ray emissions interact with the matter in the atmosphere and produce free electrons which in turn interact with a planet's magnetic field. There are no nuclear EMPs in space.<br>
The gamma radiation alone can nontheless disrupt the [[Dradis]] and [[wireless]] communication as they rely on a form of radiation as well.
In the [[Miniseries]] the EMP is shown to temporarily overload the crew's central nervous system. However, this is scientifically incorrect, since electromagnetic pulses are extremely short in duration. Moreover, while the human nervous system works with electrical currents, there is no metal to act as antenna for the magnetic field and induce a damaging current. The effects shown are either a writing error, or the result of some other force.
